Helen Newstead, head of language content at Collins, said: “The Internet age has revolutionised the inclusion of slang in dictionaries and Collins Official Scrabble Words is no exception.

"Dictionaries have always included formal and informal English, but it used to be hard to find printed evidence of the use of slang words. Now people use slang in social media posts, tweets, blogs, comments, text messages, you name it so there’s a host of evidence for informal varieties of English that simply didn’t exist before.

"We still consider electronic citations carefully before adding new words, but we’re certainly in a new and exciting era for recording a wider variety of English usage than ever before."

Allan Simmons, Scrabble consultant on Collins Official Scrabble Words, Scrabble author, and former British Scrabble Champion, added: “The wonderful thing about Scrabble is that it can be played and enjoyed across all ages, both socially and seriously.

"Players are excited when new words become available, and they’ll soon be devouring all the useful new three-letter words that are in this update. It is thought that over half of households in the UK own a Scrabble board and a reliable authority to refer to when words are challenged, and avoid those family disputes, is indispensable.

"This new update brings the renowned Collins Scrabble wordlist bang up-to-date with current usage, embracing all genres of words for young and old alike.”
